A)PDF, 907 Кб, Версия: A, Файл опубликован: 9 май 2017
Texas Instruments’ Inductive-to-Digital Converter (LDC) technology can accurately measure with a wide variety of target sizes, shapes, and material composition. There are several target design guidelines to maximize the effectiveness of an LDC measurement system. This application note covers the relevant factors of target design that affect inductive sensing, and provides guide - Measuring Rp of an L-C Sensor for Inductive SensingPDF, 205 Кб, Файл опубликован: 1 окт 2015
When designing an application using TI’s LDC series of inductive sensors, it is necessary to know the L-C sensor’s equivalent parallel resistance RP at the sensor’s resonant frequency. The RP value changes as the target is moved; the minimum RP occurs when the metal target is closest to the sensor. The maximum RP occurs when the target is at the farthest distance. Accordingly, both values should b
